And what not, and everything like that

Consider the phrases,

1) and what not

2) and everything like that

3) and what have you

and

4) whatever it may be,

The next time I hear someone utter any one of these phrases I'm going to say something about it, I'm going to ask what they mean when they say and what not, or one of the other three phrases, and why they always wait until the end of whatever they're saying to say and everything like that, what such utterances mean to them in the context of what they've already said; and then I'm going to actually listen to what they have to say.
